ABSTRACT

The present invention relates to a fabric treatment composition comprising a hydrophilic perfume and an amino-functional polymer, whereby effective perfume substantivity on the treated fabrics is obtained.

This application is a 371 of PCT/US97/18474 filed Nov. 6, 1997.

FIELD OF THE INVENTION

The present invention relates to a fabric treatment composition foreffective perfume substantivity on fabrics.

BACKGROUND OF THE INVENTION

Fabrics which exhibit a fresh scent is one of the areas of concern tothe consumers. To fulfill such need, perfumes have been incorporatedinto the compositions for domestic treatment such as in when used in theconventional laundering processes such as pre-treatment, laundry cycle,rinse cycle, tumble drying process and combination thereof. It has nowbeen found that amongst the different classes of perfumes, those whichhave a hydrophilic character provide a desirable fresh scent.

By "hydrophilic", it is meant that at least 25% by weight of the perfumecomprises perfume ingredients having a Clog P of 3 or smaller, asdefined hereinafter.

However, a problem encountered with the use of such hydrophilic perfumesis their tendency to be poorly or non- fabric substantive.

Accordingly, it is an object of the invention to provide fabrictreatment compositions comprising a hydrophilic perfume, wherebyeffective perfume substantivity on treated fabrics is obtained.

One solution to this problem is to use a sprayed composition containingsaid hydrophilic perfume, thereby applying directly the perfume to thefabric without loss of perfume upon domestic treatment. A typicaldisclosure is described in WO96/04940.

Still another solution is to use a perfume carrier such as acyclodextrin complex. A typical disclosure can be found inEP-A-0,601,035.

Notwithstanding the advances in the art, there is still a need for acomposition containing a hydrophilic perfume, and whereby effectiveperfume substantivity on fabrics is obtained.

The Applicant has now found that the provision of an amino-functionalpolymer in a composition containing a hydrophilic perfume fulfills sucha need.

Accordingly, it is an advantage of the invention to provide compositionswith effective perfume substantivity on the treated fabric.

By "effective perfume substantivity on fabrics", it is meant that abetter or equal substantivity of the perfume on the treated fabric isobtained with a composition of the invention compared to fabrics treatedwith the same perfume composition but no amino-functional polymer.

Still another advantage of the compositions is the resulting care to thecolours of the treated fabrics by the present invention compositions.

SUMMARY OF THE INVENTION

The present invention is a composition comprising a perfume and anamino-functional polymer, characterised in that at least 25% by weightof the perfume comprises perfume ingredients having a Clog P of 3 orsmaller.

In another aspect of the invention, there is provided a method forproviding color care and perfume substantivity on treated fabrics upondomestic treatment which comprises the step of contacting the fabricswith a composition comprising a perfume and an amino-functional polymer,wherein at least 25% by weight of the perfume comprises perfumeingredients having a Clog P of 3 or smaller. The contacting step mayoccur in an aqueous medium such as in a rinse cycle, pre-treatmentprocess or in a non aqueous medium such as that occurs during atumble-drying process.

DETAILED DESCRIPTION OF THE INVENTION

Amino-functional polymer

An essential component of the invention is an amino-functional polymer.Indeed, by the present component, the substantivity of the hydrophilicperfume on the treated fabric is increased. Still another advantage ofthe amino-functional polymer is that they provide care to the colors offabrics.

The amino-functional polymers of the present invention are water-solubleor dispersible, polyamines. Typically, the amino-functional polymers foruse herein have a molecular weight between 200 and 10⁶, preferablybetween 600 and 20,000, most preferably between 1000 and 10,000. Thesepolyamines comprise backbones that can be either linear or cyclic. Thepolyamine backbones can also comprise polyamine branching chains to agreater or lesser degree. Preferably, the polyamine backbones describedherein are modified in such a manner that at least one, preferably eachnitrogen of the polyamine chain is thereafter described in terms of aunit that is substituted, quaternized, oxidized, or combinationsthereof.

For the purposes of the present invention the term "modification" as itrelates to the chemical structure of the polyamines is defined asreplacing a backbone --NH hydrogen atom by an R' unit (substitution),quaternizing a backbone nitrogen (quaternized) or oxidizing a backbonenitrogen to the N-oxide (oxidized). The terms "modification" and"substitution" are used interchangably when referring to the process ofreplacing a hydrogen atom attached to a backbone nitrogen with an R'unit. Quaternization or oxidation may take place in some circumstanceswithout substitution, but substitution is preferably accompanied byoxidation or quaternization of at least one backbone nitrogen.

The linear or non-cyclic polyamine backbones that comprise theamino-functional polymer have the general formula: ##STR1##

The cyclic polyamine backbones that comprise the amino-functionalpolymer have the general formula: ##STR2##

The above backbones prior to optional but preferred subsequentmodification, comprise primary, secondary and tertiary amine nitrogensconnected by R "linking" units

For the purpose of the present invention, primary amine nitrogenscomprising the backbone or branching chain once modified are defined asV or Z "terminal" units. For example, when a primary amine moiety,located at the end of the main polyamine backbone or branching chainhaving the structure

    H.sub.2 N--R]--

is modified according to the present invention, it is thereafter definedas a V "terminal" unit, or simply a V unit. However, for the purposes ofthe present invention, some or all of the primary amine moieties canremain unmodified subject to the restrictions further described hereinbelow. These unmodified primary amine moieties by virtue of theirposition in the backbone chain remain "terminal" units. Likewise, when aprimary amine moiety, located at the end of the main polyamine back onehaving the structure

    --NH.sub.2

is modified according to the present invention, it is thereafter definedas a Z "terminal" unit, or simply a Z unit. This unit can remainunmodified subject to the restrictions further described herein below.

In a similar manner, secondary amine nitrogens comprising the backboneor branching chain once modified are defined as W "backbone" units. Forexample, when a secondary amine moiety, the major constituent of thebackbones and branching chains of the present invention, having thestructure ##STR3## is modified according to the present invention, it isthereafter defined as a W "backbone" unit, or simply a W unit. However,for the purposes of the present invention, some or all of the secondaryamine moieties can remain unmodified. These unmodified secondary aminemoieties by virtue of their position in the backbone chain remain"backbone" units.

In a further similar manner, tertiary amine nitrogens comprising thebackbone or branching chain once modified are further referred to as Y"branching" units. For example, when a tertiary amine moiety, which is achain branch point of either the polyamine backbone or other branchingchains or rings, having the structure ##STR4## is modified according tothe present invention, it is thereafter defined as a Y "branching" unit,or simply a Y unit. However, for the purposes of the present invention,some or all or the tertiary amine moieties can remain unmodified. Theseunmodified tertiary amine moieties by virtue of their position in thebackbone chain remain "branching" units. The R units associated with theV, W and Y unit nitrogens which serve to connect the polyaminenitrogens, are described herein below.

The final modified structure of the polyamines of the present inventioncan be therefore represented by the general formula

    V.sub.(n+1) W.sub.m Y.sub.n Z

for linear amino-functional polymer and by the general formula

    V.sub.(n-k+1) W.sub.m Y.sub.n Y'.sub.k Z

for cyclic amino-functional polymer. For the case of polyaminescomprising rings, a Y' unit of the formula ##STR5## serves as a branchpoint for a backbone or branch ring. For every Y' unit there is a Y unithaving the formula ##STR6## that will form the connection point of thering to the main polymer chain or branch. In the unique case where thebackbone is a complete ring, the polyamine backbone has the formula##STR7## therefore comprising no Z terminal unit and having the formula

    V.sub.n-k W.sub.m Y.sub.n Y'.sub.k

wherein k is the number of ring forming branching units. Preferably thepolyamine backbones of the present invention comprise no rings.

In the case of non-cyclic polyamines, the ratio of the index n to theindex m relates to the relative degree of branching. A fullynon-branched linear modified polyamine according to the presentinvention has the formula that is, n is equal to 0. The greater thevalue of n (the lower the ratio of m to n), the greater the degree ofbranching in the molecule. Typically the value for m ranges from aminimum value of 2 to 700, preferably 4 to 400, however larger values ofm, especially when the value of the index n is very low or nearly 0, arealso preferred.

Each polyamine nitrogen whether primary, secondary or tertiary, oncemodified according to the present invention, is further defined as beinga member of one of three general classes; simple substituted,quaternized or oxidized. Those polyamine nitrogen units not modified areclassed into V, W, Y, Y' or Z units depending on whether they areprimary, secondary or tertiary nitrogens. That is unmodified primaryamine nitrogens are V or Z units, unmodified secondary amine nitrogensare W units or Y' units and unmodified tertiary amine nitrogens are Yunits for the purposes of the present invention.

Modified primary amine moieties are defined as V "terminal" units havingone of three forms:

a) simple substituted units having the structure: ##STR8## b)quaternized units having the structure: ##STR9## wherein X is a suitablecounter ion providing charge balance; and c) oxidized units having thestructure: ##STR10##

Modified secondary amine moieties are defined as W "backbone" unitshaving one of three forms:

a) simple substituted units having the structure: ##STR11## b)quaternized units having the structure: ##STR12## wherein X is asuitable counter ion providing charge balance; and c) oxidized unitshaving the structure: ##STR13##

Other modified secondary amine moieties are defined as Y' units havingone of three forms:

a) simple substituted units having the structure: ##STR14## b)quaternized units having the structure: ##STR15## wherein X is asuitable counter ion providing charge balance; and c) oxidized unitshaving the structure: ##STR16##

Modified tertiary amine moieties are defined as Y "branching" unitshaving one of three forms:

a) unmodified units having the structure: ##STR17## b) quaternized unitshaving the structure: ##STR18## wherein X is a suitable counter ionproviding charge balance; and c) oxidized units having the structure:##STR19##

Certain modified primary amine moieties are defined as Z "terminal"units having one of three forms:

a) simple substituted units having the structure: ##STR20## b)quaternized units having the structure: ##STR21## wherein X is asuitable counter ion providing charge balance; and c) oxidized unitshaving the structure: ##STR22##

When any position on a nitrogen is unsubstituted of unmodified, it isunderstood that hydrogen will substitute for R'. For example, a primaryamine unit comprising one R' unit in the form of a hydroxyethyl moietyis a V terminal unit having the formula (HOCH₂ CH₂)HN--.

For the purposes of the present invention there are two types of chainterminating units, the V and Z units. The Z "terminal" unit derives froma terminal primary amino moiety of the structure --NH₂. Non-cyclicpolyamine backbones according to the present invention comprise only oneZ unit whereas cyclic polyamines can comprise no Z units. The Z"terminal" unit can be substituted with any of the R' units describedfurther herein below, except when the Z unit is modified to form anN-oxide. In the case where the Z unit nitrogen is oxidized to anN-oxide, the nitrogen must be modified and therefore R' cannot be ahydrogen.

The polyamines of the present invention comprise backbone R "linking"units that serve to connect the nitrogen-atoms of the backbone. R unitscomprise units that for the purposes of the present invention arereferred to as "hydrocarbyl R" units and "oxy R" units. The"hydrocarbyl" R units are C₂ -C₁₂ alkylene, C₄ -C₁₂ alkenylene, C₃ -C₁₂hydroxyalkylene wherein the hydroxyl moiety may take any position on theR unit chain except the carbon atoms directly connected to the polyaminebackbone nitrogens; C₄ -C₁₂ dihydroxyalkylene wherein the hydroxylmoieties may occupy any two of the carbon atoms of the R unit chainexcept those carbon atoms directly connected to the polyamine backbonenitrogens; C₈ -C₁₂ dialkylarylene which for the purpose of the presentinvention are arylene moieties having two alkyl substituent groups aspart of the linking chain. For example, a dialkylarylene unit has theformula ##STR23## although the unit need not be 1,4-substituted, but canalso be 1,2 or 1,3 substituted C₂ -C₁₂ alkylene, preferably ethylene,1,2-propylene, and mixtures thereof, more preferably ethylene. The "oxy"R units comprise --(R¹ O)_(x) R⁵ (OR¹)_(x) --, --CH₂ CH(OR²)CH₂ O)_(z)(R¹ O)_(y) R¹ (OCH₂ CH(OR²)CH₂)_(w) --, --CH₂ CH(OR²)CH₂ --, --(R¹O)_(x) R¹ --, and mixtures thereof.

The preferred "oxy" R units are further defined in terms of the R¹, R²,and R⁵ units. Preferred "oxy" R units comprise the preferred R¹, R², andR⁵ units. The preferred cotton soil release agents of the presentinvention comprise at least 50% R¹ units that are ethylene. PreferredR¹, R², and R⁵ units are combined with the "oxy" R units to yield thepreferred "oxy" R units in the following manner.

i) Substituting more preferred R⁵ into --(CH₂ CH₂ O)_(x) R⁵ (OCH₂CH₂)_(x) -- yields --(CH₂ CH₂ O)_(X) CH₂ CHOHCH₂ (OCH₂ CH₂)_(x) --.

iii) Substituting preferred R² into --CH₂ CH(OR²)CH₂ -- yields --CH₂CH(OH)CH₂ --.

R' units are selected from the group consisting of hydrogen, C₁ -C₂₂alkyl, C₃ -C₂₂ alkenyl, C₇ -C₂₂ arylalkyl, C₂ -C₂₂ hydroxyalkyl,--(CH₂)_(p) CO₂ M, --(CH₂)_(q) SO₃ M, --CH(CH₂ CO₂ M)CO₂ M, --(CH₂)_(p)PO₃ M, --(R¹ O)_(m) B, --C(O)R³, preferably hydrogen, C₂ -C₂₂hydroxyalkylene, benzyl, C₁ -C₂₂ alkylene, --(R¹ O)_(m) B, --C(O)R³,--(CH₂)_(p) CO₂ M, --(CH₂)_(q) SO₃ M, --CH(CH₂ CO₂ M)CO₂ M, morepreferably C₁ -C₂₂ alkylene, (R¹ O)_(x) B, --C(O)R³, --(CH₂)_(p) CO₂ M,--(CH₂)_(q) SO₃ M, --CH(CH₂ CO₂ M)CO₂ M, most preferably C₁ -C₂₂alkylene, --(R¹ O)_(x) B, and --C(O)R³. When no modification orsubstitution is made on a nitrogen then hydrogen atom will remain as themoiety representing R'. R' units do not comprise hydrogen atom when theV, W or Z units are oxidized, that is the nitrogens are N-oxides. Forexample, the backbone chain or branching chains do not comprise units ofthe following structure: ##STR24##

Additionally, R' units do not comprise carbonyl moieties directly bondedto a nitrogen atom when the V, W or Z units are oxidized, that is, thenitrogens are N-oxides. According to the present invention, the R' unit--C(O)R³ moiety is not bonded to an N-oxide modified nitrogen, that is,there are no N-oxide amides having the structure ##STR25## orcombinations thereof.

B is hydrogen, C₁ -C₆ alkyl, --(CH₂)_(q) SO₃ M, --(CH₂)_(p) CO₂ M,--(CH₂)_(q) --(CHSO₃ M)CH₂ SO₃ M, --(CH₂)_(q) (CHSO₂ M)CH₂ SO₃ M,--(CH₂)_(p) PO₃ M, --PO₃ M, preferably hydrogen, --(CH₂)_(q) SO₃ M,--(CH₂)_(q) (CHSO₃ M)CH₂ SO₃ M, --(CH₂)_(q) --(CHSO₂ M)CH₂ SO₃ M, morepreferably hydrogen or --(CH₂)_(q) SO₃ M.

M is hydrogen or a water soluble cation in sufficient amount to satisfycharge balance. For example, a sodium cation equally satisfies--(CH₂)_(p) CO₂ M, and --(CH₂)_(q) SO₃ M, thereby resulting in (CH₂)_(p)CO₂ Na, and --(CH₂)_(q) SO₃ Na moieties. More than one monovalentcation, (sodium, potassium, etc.) can be combined to satisfy therequired chemical charge balance. However, more than one anionic groupmay be charge balanced by a divalent cation, or more than onemono-valent cation may be necessary to satisfy the charge requirementsof a poly-anionic radical. For example, a --(CH₂)_(p) PO₃ M moietysubstituted with sodium atoms has the formula --(CH₂)_(p) PO₃ Na₃.Divalent cations such as calcium (Ca²⁺) or magnesium (Mg²⁺) may besubstituted for or combined with other suitable mono-valent watersoluble cations. Preferred cations are sodium and potassium, morepreferred is sodium.

X is a water soluble anion such as chlorine (Cl⁻), bromine (Br⁻) andiodine (I⁻) or X can be any negatively charged radical such as sulfate(SO₄ ²⁻) and methosulfate (CH₃ SO₃₋).

The formula indices have the following values: p has the value from 1 to6, q has the value from 0 to 6; r has the value 0 or 1; w has the value0 or 1, x has the value from 1 to 100; y has the value from 0 to 100; zhas the value 0 or 1; m has the value from 2 to 700, preferably from 4to 400, n has the value from 0 to 350, preferably from 0 to 200; m+n hasthe value of at least 5.

Preferably x has a value lying in the range of from 1 to 20, preferablyfrom 1 to 10.

The preferred amino-functional polymers of the present inventioncomprise polyamine backbones wherein less than 50% of the R groupscomprise "oxy" R units, preferably less than 20% , more preferably lessthan 5%, most preferably the R units comprise no "oxy" R units.

The most preferred amino-functional polymers which comprise no "oxy" Runits comprise polyamine backbones wherein less than 50% of the R groupscomprise more than 3 carbon atoms. For example, ethylene, 1,2-propylene,and 1,3-propylene comprise 3 or less carbon atoms and are the preferred"hydrocarbyl" R units. That is when backbone R units are C₂ -C₁₂alkylene, preferred is C₂ -C₃ alkylene, most preferred is ethylene.

The amino-functional polymers of the present invention comprise modifiedhomogeneous and non-homogeneous polyamine backbones, wherein 100% orless of the --NH units are modified. For the purpose of the presentinvention the term "homogeneous polyamine backbone" is defined as apolyamine backbone having R units that are the same (i.e., allethylene). However, this sameness definition does not exclude polyaminesthat comprise other extraneous units comprising the polymer backbonewhich are present due to an artifact of the chosen method of chemicalsynthesis. For example, it is known to those skilled in the art thatethanolamine may be used as an "initiator" in the synthesis ofpolyethyleneimines, therefore a sample of polyethyleneimine thatcomprises one hydroxyethyl moiety resulting from the polymerization"initiator" would be considered to comprise a homogeneous polyaminebackbone for the purposes of the present invention. A polyamine backbonecomprising all ethylene R units wherein no branching Y units are presentis a homogeneous backbone. A polyamine backbone comprising all ethyleneR units is a homogeneous backbone regardless of the degree of branchingor the number of cyclic branches present.

For the purposes of the present invention the term "non-homogeneouspolymer backbone" refers to polyamine backbones that are a composite ofvarious R unit lengths and R unit types. For example, a non-homogeneousbackbone comprises R units that are a mixture of ethylene and1,2-propylene units. For the purposes of the present invention a mixtureof "hydrocarbyl" and "oxy" R units is not necessary to provide anon-homogeneous backbone.

Preferred amino-functional polymers of the present invention comprisehomogeneous polyamine backbones that are totally or partiallysubstituted by polyethyleneoxy moieties, totally or partiallyquaternized amines, nitrogens totally or partially oxidized to N-oxides,and mixtures thereof. However, not all backbone amine nitrogens must bemodified in the same manner, the choice of modification being left tothe specific needs of the formulator. The degree of ethoxylation is alsodetermined by the specific requirements of the formulator.

The preferred polyamines that comprise the backbone of the compounds ofthe present invention are generally polyalkyleneimines (PAI's),preferably polyethyleneimines (PEI's), or PEI's connected by moietieshaving longer R units than the parent PAI's or PEI's.

Preferred amine polymer backbones comprise R units that are C₂ alkylene(ethylene) units, also known as polyethylenimines (PEI's). PreferredPEI's have at least moderate branching, that is the ratio of m to n isless than 4:1, however PEI's having a ratio of m to n of 2:1 are mostpreferred. Preferred backbones, prior to modification have the generalformula: ##STR26## wherein R', m and n are the same as defined hereinabove. Preferred PEI's will have a molecular weight greater than 200daltons.

The relative proportions of primary, secondary and tertiary amine unitsin the polyamine backbone, especially in the case of PEI's, will vary,depending on the manner of preparation. Each hydrogen atom attached toeach nitrogen atom of the polyamine backbone chain represents apotential site for subsequent substitution, quaternization or oxidation.

These polyamines can be prepared, for example, by polymerizingethyleneimine in the presence of a catalyst such as carbon dioxide,sodium bisulfite, sulfuric acid, hydrogen peroxide, hydrochloric acid,acetic acid, etc. Specific methods for preparing these polyaminebackbones are disclosed in U.S. Pat. No. 2,182,306, Ulrich et al.,issued Dec. 5, 1939; U.S. Pat. No. 3,033,746, Mayle et al., issued May8, 1962; U.S. Pat. No. 2,208,095, Esselmann et al., issued Jul. 16,1940; U.S. Pat. No. 2,806,839, Crowther, issued Sep. 17, 1957; and U.S.Pat. No. 2,553,696, Wilson, issued May 21, 1951; all herein incorporatedby reference.

Examples of amino-functional polymers comprising PEI's, are illustratedin Formulas I--IV:

Formula I depicts an amino-functional polymer comprising a PEI backbonewherein all substitutable nitrogens are modified by replacement ofhydrogen with a polyoxyalkyleneoxy unit, --(CH₂ CH₂ O)H, having theformula ##STR27##

This is an example of an amino-functional polymer that is fully modifiedby one type of moiety.

Formula II depicts an amino-functional polymer comprising a PEI backbonewherein all substitutable primary amine nitrogens are modified byreplacement of hydrogen with a polyoxyalkyleneoxy unit, --(CH₂ CH₂ O)₂H, the molecule is then modified by subsequent oxidation of alloxidizable primary and secondary nitrogens to N-oxides, said polymerhaving the formula ##STR28##

Formula III depicts an amino-functional polymer comprising a PEIbackbone wherein all backbone hydrogen atoms are substituted and somebackbone amine units are quaternized. The substituents arepolyoxyalkyleneoxy units, --(CH₂ CH₂ O)₇ H, or methyl groups. Themodified PEI has the formula ##STR29##

Formula IV depicts an amino-functional polymer comprising a PEI backbonewherein the backbone nitrogens are modified by substitution (i.e. by--(CH₂ CH₂ O)₃ H or methyl) quaternized, oxidized to N-oxides orcombinations thereof. The resulting polymer has the formula ##STR30##

In the above examples, not all nitrogens of a unit class comprise thesame modification. The present invention allows the formulator to have aportion of the secondary amine nitrogens ethoxylated while having othersecondary amine nitrogens oxidized to N-oxides. This also applies to theprimary amine nitrogens, in that the formulator may choose to modify ailor a portion of the primary amine nitrogens with one or moresubstituents prior to oxidation or quaternization. Any possiblecombination of R' groups can be substituted on the primary and secondaryamine nitrogens, except for the restrictions described herein above.

For the perfume to be hydrophilic, at least 25% by weight of theperfume, more preferably at least 50%, most preferably at least 75%, iscomposed of perfume ingredients that are hydrophilic, i.e having a ClogP of 3 or smaller as defined hereinafter.

The degree of hydrophobicity or hydrophilicity of a perfume ingredientcan be correlated with its octanol/water partitioning coefficient P. Theoctanol/water partitioning coefficient of a perfume ingredient is theratio between its equilibrium concentration in octanol and in water. Aperfume ingredient with a greater partitioning coefficient P is morehydrophobic.

Conversely, a perfume ingredient with a smaller partitioning coefficientP is more hydrophilic. The preferred perfume ingredients of thisinvention have an octanol/water partitioning coefficient P of 1,000 orsmaller. Since the partitioning coefficients of the perfume ingredientsnormally have high values, they are more conveniently given in the formof their logarithm to the base 10, logP.

The logP of many perfume ingredients has been reported; for example, inthe Pomona 92 database, available from Daylight Chemical InformationSystems, Inc. (Daylog CIS), Irvine, Calif., contains many, along withcitations to the original literature. However, the logP values are mostconveniently calculated by the "CLOG P" program, also available fromDaylight CIS. This program also lists experimental logP values when theyare available in the Pomona 92 database. The "calculated logP" (Clog P)is determined by the fragment approach of Hansch and Leo (cf., A. Leo,in Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G. Sammens,J. B. Taylor and C. A. Ramsden, Eds., p. 295, Pergamon Press, 1990,incorporated herein by reference). The fragment approach is based on thechemical structure of each perfume ingredient, and takes into accountthe numbers and types of atoms, the atom connectivity, and chemicalbonding. The Clog P values, which are the most reliable and widely usedestimates for this physicochemical property, are used instead of theexperimental logP values in the selection of perfume ingredients whichare useful in the present invention.

For use herein, preferred perfume ingredients having a Clog P of about 3or smaller are selected from the group consisting of benzaldehyde,benzyl acetate, cis-3-hexenyl acetate, coumarin, dihydromyrcenol,dimethyl benzyl carbinyl acetate, ethyl vanillin, eucalyptol, eugenol,iso eugenol, flor acetate, geraniol, hydroxycitronellal, koavone,linalool, methyl anthranilate, methyl beta naphthyl ketone, methyldihydro jasmonate, nerol, nonalactone, phenyl ethyl acetate, phenylethyl alcohol, alpha terpineol, beta terpineol, vanillin, and mixturesthereof.

Preferably the composition contains an effective amount of perfume toprovide the freshening fragrance to fabrics, some lingering fragrancein-wear, and some extra fragrance to be released upon fabric rewetting.

Effective level of perfume is from 0.001% to 5.0%, more preferably from0.01% to 2.0%, most preferably from 0.015% to 0.5%, by weight of thecomposition.

Depending on the end use, the composition may also contain optionalcomponents which maybe suitable for further improving the aestheticappearance of the fabrics treated therewith. Suitable optionalcomponents are selected from the group consisting of a dye fixing agent,a polyolefin dispersion, non-polymeric chlorine scavenger, a fabricsoftener component, enzymes, detersive ingredients, additionalcomponents and mixtures thereof.

Dye Fixing Agent

An optional component of the invention is a dye fixing agent. Dye fixingagents, or "fixatives", are well-known, commercially available materialswhich are designed to improve the appearance of dyed fabrics byminimizing the loss of dye from fabrics due to washing. Not includedwithin this definition are components which are fabric softeners orthose described hereinafter as amino-functional polymers.

Many dye fixing agents are cationic, and are based on variousquaternized or otherwise cationically charged organic nitrogencompounds. Cationic fixatives are available under various trade namesfrom several suppliers. Representative examples include: CROSCOLOR PMF(July 1981, Code No. 7894) and CROSCOLOR NOFF (January 1988, Code No.8544) from Crosfield; INDOSOL E-50 (Feb. 27, 1984, Ref. No. 6008.35.84;polyethyleneamine-based) from Sandoz; SANDOFIX TPS, which is alsoavailable from Sandoz and is a preferred polycationic fixative for useherein and SANDOFIX SWE (cationic resinous compound), REWIN SRF, REWINSRF-0 and REWIN DWR from CHT-Beitlich GMBH, Tinofix® ECO, Tinofix®FRDand Solfin® available from Ciba-Geigy.

Other cationic dye fixing agents are described in "Aftertreatments forimproving the fastness of dyes on textile fibres" by Christopher C. Cook(REV. PROG. COLORATION Vol. 12, 1982). Dye fixing agents suitable foruse in the present invention are ammonium compounds such as fattyacid--diamine condensates e.g. the hydrochloride, acetate, metosulphateand benzyl hydrochloride of oleyldiethyl aminoethylamide,oleylmethyl-diethylenediaminemethosulphate, monostearyl-ethylenediaminotrimethylammonium methosulphate and oxidized products of tertiaryamines; derivatives of polymeric alkyldiamines, polyamine-cyanuricchloride condensates and aminated glycerol dichlorohydrins.

A typical amount of the dye fixing agent to be employed in thecomposition of the invention is preferably up 90% by weight, preferablyup to 50% by weight, more preferably from 0.001% to 10% by weight, mostpreferably from 0.5% to 5% active by weight of the composition.

Polyolefin Dispersion

A polyolefin dispersion may optionally be used in the composition of theinvention in order to provide anti-wrinkles and improved waterabsorbency benefits to the fabrics. Preferably, the polyolefin is apolyethylene, polypropylene or mixtures thereof. The polyolefin may beat least partially modified to contain various functional groups, suchas carboxyl, carbonyl, ester, ether, alkylamide, sulfonic acid or amidegroups. More preferably, the polyolefin employed in the presentinvention is at least partially carboxyl modified or, in other words,oxidized. In particular, oxidized or carboxyl modified polyethylene ispreferred in the compositions of the present invention.

For ease of formulation, the polyolefin is preferably introduced as asuspension or an emulsion o f polyolefin dispersed by use of anemulsifing agent. The polyolefin suspension or emulsion preferably hasfrom 1 to 50%, more preferably from 10 to 35% by weight, and mostpreferably from 15 to 30% by weight of polyolefin in the emulsion. Thepolyolefin preferably has a molecular weight of from 1,000 to 15,000 andmore preferably from 4,000 to 10,000.

When an emulsion is employed, the emulsifier may be any suitableemulsification or suspending agent. Preferably, the emulsifier is acationic, nonionic, zwitterionic or anionic surfactant or mixturesthereof. Most preferably, any suitable cationic, nonionic or anionicsurfactant may be employed as the emulsifier. Preferred emulsifiers arecationic surfactants such as the fatty amine surfactants and inparticular the ethoxylated fatty amine surfactants. In particular, thecationic surfactants are preferred as emulsifiers in the presentinvention. The polyolefin is dispersed with the emulsifier or suspendingagent in a ratio of emulsifier to polyolefin of from 1:10 to 3:1.Preferably, the emulsion includes from 0.1 to 50%, more preferably from1 to 20% and most preferably from 2.5 to 10% by weight of emulsifier inthe polyolefin emulsion.

When the polyolefin is added to thecompositions of the present invention as an emulsion or suspension, theemulsion or suspension is added at sufficient enough quantities toprovide the above noted levels of dispersible polyolefin in thecompositions.

Non-polymeric Chlorine Scavengers

A non-polymeric chlorine scavenger is another optional component of theinvention.

Suitable levels of chlorine scavengers in the compositions of thepresent invention may range from 0.01% to 15%, preferably from 0.02% to10%, most preferably from 0.25% to 5%, by weight of total composition.If both the cation and the anion of the scavenger react with chlorine,which is desirable, the level may be adjusted to react with anequivalent amount of available chlorine.

The chlorine Scavengers for use herein are selected from the groupconsisting of non-polymeric ammonium salts. Suitable non-polymericammonium salts for use herein have the general formula:

Fabric Softener Component

Optionally, a fabric softener component may also be suitably used in thecomposition of the invention so as to provide softness and antistasticproperties to the treated fabrics. When used, the fabric softenercomponent will typically be present at a level sufficient to providesoftening and antistatic properties. Typical levels are thoseconventionally used in fabric softening compositions, i.e from 1% to 99%by weight of the composition. Depending on the composition execution,i.e liquid or solid, the composition will preferably comprise a level offabric softening components for liquid compositions of from 1% to 5% byweight for the diluted compositions or from 5% to 80%, more preferably10% to 50%, most preferably 15% to 35% by weight for concentratedcompositions. Where nonionic fabric softener components are present, thelevel of nonionic softener component in the composition will typicallybe from 0.1% to 10%, preferably from 1% to 5% by weight.

Where the composition comprising the softener component is applied on asubstrate such as a dryer-sheet, the preferred level of fabric softenercomponent will preferably be from 20% to 99%, more preferably from 30%to 90% by weight, and even more preferably from 35% to 85% by weight.

Said fabric softening component may be selected from cationic, nonionic,amphoteric or anionic fabric softening component.

The preferred, typical cationic fabric softening components include thewater-insoluble quaternary-ammonium fabric softening actives, the mostcommonly used having been di-long alkyl chain ammonium chloride ormethyl sulfate.

Preferred cationic softeners among these include the following:

1) ditallowyl dimethylammonium chloride (DTDMAC);

2) dihydrogenated tallow dimethylammonium chloride;

10) ditallow imidazolinium methylsulfate;

11) 1-(2-tallowylamidoethyl)-2-tallowyl imidazolinium methylsulfate.

However, in recent years, the need has arisen for moreenvironmentally-friendly materials, and rapidly biodegradable quaternaryammonium compounds have been presented as alternatives to thetraditionally used di-long alkyl chain ammonium chlorides and methylsulfates. Said materials and fabric softening compositions containingthem are disclosed in numerous publications such as EP-A-0,040,562, andEP-A-0,239,910.

The quaternary ammonium compounds and amine precursors herein have theformula (I) or (II), below: ##STR31## wherein Q is selected from--O--C(O)--, --C(O)--O--, --O--C(O)--O--, --NR⁴ --C(O)--, --C(O)--NR⁴--;

R¹ is (CH₂)n--Q--T² or T³ ;

R² is (CH₂)m--Q--T⁴ or T⁵ or R³ ;

R³ is C₁ -C₄ alkyl or C₁ -C₄ hydroxyalkyl or H;

R⁴ is H or C₁ -C₄ alkyl or C₁ -C₄ hydroxyalkyl;

T¹, T², T³, T⁴, T⁵ are independently C₆ -C₂₂ alkyl or alkenyl;

n and m are integers from 1 to 4; and

X⁻ is a softener-compatible anion.

Non-limiting examples of softener-compatible anions include chloride ormethyl sulfate.

The alkyl, or alkenyl, chain T¹, T², T³, T⁴, T⁵ must contain at least 6carbon atoms, preferably at least 11 carbon atoms, more preferably atleast 16 carbon atoms. The chain may be straight or branched.

Tallow is a convenient and inexpensive source of long chain alkyl andalkenyl material. The compounds wherein T¹, T², T³, T⁴, T⁵ representsthe mixture of long chain materials typical for tallow are particularlypreferred.

Specific examples of quaternary ammonium compounds suitable for use inthe aqueous fabric softening compositions herein include:

1) N,N-di(tallowoyl-oxy-ethyl)-N,N-dimethyl ammonium chloride;

2) N,N-di(tallowoyl-oxy-ethyl)-N-methyl, N-(2-hydroxyethyl) ammoniummethyl sulfate;

3) N,N-di(tallowyl-oxy-2-oxo-ethyl)-N,N-dimethyl ammonium chloride;

4) N,N-di(tallowyl-oxy-ethylcarbonyl-oxy-ethyl)-N,N-dimethyl ammoniumchloride;

5) N-(tallowoyl-oxy-2-ethyl)-N-(tallowyl-oxy-2-oxo-ethyl)-N,N-dimethylammonium chloride;

6) N,N,N-tri(tallowoyl-oxy-ethyl)-N-methyl ammonium chloride;

7) N-(tallowyl-oxy-2-oxo-ethyl)-N-tallowyl-N,N-dimethyl-ammoniumchloride; and

8) 1,2-ditallowoyl-oxy-3-trimethylammoniopropane chloride;

9) di(stearoyloxyethyl) dimethylammonium chloride (DSOEDMAC); andmixtures of any of the above materials.

Of these, compounds 1-7 are examples of compounds of Formula (I);compound 8 is a compound of Formula (II).

Particularly preferred is N,N-di(tallowoyl-oxy-ethyl)-N,N-dimethylammonium chloride, where the tallow chains are at least partiallyunsaturated.

The level of unsaturation of the fatty chain can be measured by theIodine Value (IV) of the corresponding fatty acid, which in the presentcase should preferably be in the range of from 5 to 200, preferably 5 to150, and more preferably 5 to 100 with two categories of compounds beingdistinguished, having a IV below or above 25.

Indeed, for compounds of Formula (I) made from tallow fatty acids havinga IV of from 5 to 25, preferably 15 to 20, it has been found that acis/trans isomer weight ratio greater than 30/70, preferably greaterthan 50/50 and more preferably greater than 70/30 provides optimalconcentrability.

For compounds of Formula (I) made from tallow fatty acids having a IV ofabove 25, the ratio of cis to trans isomers has been found to be lesscritical unless very high concentrations are needed.

Other examples of suitable quaternary ammoniums of Formula (I) and (II)are obtained by, e.g.

replacing "tallow" in the above compounds with, for example, coco, palm,lauryl, oleyl, ricinoleyl, stearyl, palmityl, or the like, said fattyacyl chains being either fully saturated, or preferably at least partlyunsaturated;

replacing "methyl" in the above compounds with ethyl, ethoxy, propyl,propoxy, isopropyl, butyl, isobutyl or t-butyl;

replacing "chloride" in the above compounds with bromide, methylsulfate,formate, sulfate, nitrate, and the like.

In fact, the anion is merely present as a counterion of the positivelycharged quaternary ammonium compounds. The nature of the counterion isnot critical at all to the practice of the present invention. The scopeof this invention is not considered limited to any particular anion.

By "amine precursors thereof" is meant the secondary or tertiary aminescorresponding to the above quaternary ammonium compounds, said aminesbeing substantially protonated in the present compositions due to the pHvalues.

Additional fabric softening materials may be used in addition oralternatively to the cationic fabric softener. These may be selectedfrom nonionic, amphoteric or anionic fabric softening material.Disclosure of such materials may be found in U.S. Pat. No. 4,327,133;U.S. Pat. No. 4,421,792; U.S. Pat. No. 4,426,299; U.S. Pat. No.4,460,485; U.S. Pat. No. 3,644,203; U.S. Pat. No. 4,661,269; U.S. Pat.No. 4,439,335; U.S. Pat. No. 3,861,870; U.S. Pat. No. 4,308,151; U.S.Pat. No. 3,886,075; U.S. Pat. No. 4,233,164; U.S. Pat. No. 4,401,578;U.S. Pat. No. 3,974,076; U.S. Pat. No. 4,237,016 and EP 472,178.

Typically, such nonionic fabric softener materials have a HLB of from 2to 9, more typically from 3 to 7. Such nonionic fabric softenermaterials tend to be readily dispersed either by themselves, or whencombined with other materials such as single-long-chain alkyl cationicsurfactant described in detail hereinafter. Dispersibility can beimproved by using more single-long-chain alkyl cationic surfactant,Mixture with other materials as set forth hereinafter, use of hotterwater, and/or more agitation. In general, the materials selected shouldbe relatively crystalline, higher melting, (e.g. >40° C.) and relativelywater-insoluble.

Preferred nonionic softeners are fatty acid partial esters of polyhydricalcohols, or anhydrides thereof, wherein the alcohol, or anhydride,contains from 2 to 18, preferably from 2 to 8, carbon atoms, and eachfatty acid moiety contains from 12 to 30, preferably from 16 to 20,carbon atoms. Typically, such softeners contain from one to 3,preferably 2 fatty acid groups per molecule.

The polyhydric alcohol portion of the ester can be ethylene glycol,glycerol, poly (e.g., di-, tri-, tetra, penta-, and/or hexa-) glycerol,xylitol, sucrose, erythritol, pentaerythritol, sorbitol or sorbitan.Sorbitan esters and polyglycerol monostearate are particularlypreferred.

The fatty acid portion of the ester is normally derived from fatty acidshaving from 12 to 30, preferably from 16 to 20, carbon atoms, typicalexamples of said fatty acids being lauric acid, myristic acid, palmiticacid, stearic acid and behenic acid.

Highly preferred optional nonionic softening agents for use in thepresent invention are the sorbitan esters, which are esterifieddehydration products of sorbitol, and the glycerol esters.

Commercial sorbitan monostearate is a suitable material. Mixtures ofsorbitan stearate and sorbitan palmitate having stearate/palmitateweight ratios varying between 10:1 and 1:10, and 1,5-sorbitan esters arealso useful.

Glycerol and polyglycerol esters, especially glycerol, diglycerol,triglycerol, and polyglycerol mono- and/or di-esters, preferably mono-,are preferred herein (e.g. polyglycerol monostearate with a trade nameof Radiasurf 7248).

Useful glycerol and polyglycerol esters include mono-esters withstearic, oleic, palmitic, lauric, isostearic, myristic, and/or behenicacids and the diesters of stearic, oleic, palmitic, lauric, isostearic,behenic, and/or myristic acids. It is understood that the typicalmono-ester contains some di- and tri-ester, etc.

The "glycerol esters" also include the polyglycerol, e.g., diglycerolthrough octaglycerol esters. The polyglycerol polyols are formed bycondensing glycerin or epichlorohydrin together to link the glycerolmoieties via ether linkages. The mono- and/or diesters of thepolyglycerol polyols are preferred, the fatty acyl groups typicallybeing those described hereinbefore for the sorbitan and glycerol esters.

For the preceding fabric softening agents, especially with biodegradablefabric softening agents, the pH of the liquid compositions herein is anessential parameter of the present invention. Indeed, it influences thestability of the quaternary ammonium or amine precursors compounds,especially in prolonged storage conditions. The pH, as defined in thepresent context, is measured in the neat compositions at 20° C. Foroptimum hydrolytic stability of the se compositions, the neat pH,measured in the above-mentioned conditions, must be in the range of from2.0 to 4.5. Preferably, where the liquid fabric softening compositionsof the invention are in a concentrated form, the pH of the neatcomposition is in the range of 2.0 to 3.5, while if it is in a dilutedform, the pH of the neat composition is in the range of 2.0 to 3.0. ThepH of these compositions herein can be regulated by the addition of aBronsted acid.

Examples of suitable acids include the inorganic mineral acids,carboxylic acids, in particular the low molecular weight (C₁ -C₅)carboxylic acids, and alkylsulfonic acids. Suitable inorganic acidsinclude HCl, H₂ SO₄, HNO₃ and H₃ PO₄. Suitable organic acids includeformic, acetic, citric, methylsulfonic and ethylsulfonic acid. Preferredacids are citric, hydrochloric, phosphoric, formic, methylsulfonic acid,and benzoic acids.

Enzymes

The composition herein can optionally employ one or more enzymes such aslipases, proteases, cellulase, amylases and peroxidases. A preferredenzyme for use herein is a cellulase enzyme. Indeed, this type of enzymewill further provide a color care benefit to the treated fabric.Cellulases usable herein include both bacterial and fungal types,preferably having a pH optimum between 5 and 9.5. U.S. Pat. No.4,435,307, Barbesgoard et al, Mar. 6, 1984, discloses suitable fungalcellulases from Humicola insolens or Humicola strain DSM1800 or acellulase 212-producing fungus belonging to the genus Aeromonas, andcellulase extracted from the hepatopancreas of a marine mollusk,Dolabella Auricula Solander. Suitable cellulases are also disclosed inGB-A-2.075.028; GB-A-2.095.275 and DE-OS-2.247.832. CAREZYME® andCELLUZYME® (Novo) are especially useful. Other suitable cellulases arealso disclosed in WO 91/17243 to Novo, WO 96/34092, WO 96/34945 andEP-A-0,739,982.

In practical terms for current commercial preparations, typical amountsare up to about 5 mg by weight, more typically 0.01 mg to 3 mg, ofactive enzyme per gram of the composition. Stated otherwise, thecompositions herein will typically comprise from 0.001% to 5%,preferably 0.01%-1% by weight of a commercial enzyme preparation. In theparticular cases where activity of the enzyme preparation can be definedotherwise such as with cellulases, corresponding activity units arepreferred (e.g. CEVU or cellulase Equivalent Viscosity Units). Forinstance, the compositions of the present invention can containcellulase enzymes at a level equivalent to an activity from about 0.5 to1000 CEVU/gram of composition. Cellulase enzyme preparations used forthe purpose of formulating the compositions of this invention typicallyhave an activity comprised between 1,000 and 10,000 CEVU/gram in liquidform, around 1,000 CEVU/gram in solid form.

Fully formulated fabric softening compositions preferably contain, inaddition to the hereinbefore described components, one or more of thefollowing ingredients.

Concentrated compositions of the present invention may require organicand/or inorganic concentration aids to go to even higher concentrationsand/or to meet higher stability standards depending on the otheringredients. Surfactant concentration aids are typically selected fromthe group consisting of single long chain alkyl cationic surfactants;nonionic surfactants; amine oxides; fatty acids; or mixtures thereof,typically used at a level of from 0 to 15% of the composition.

Inorganic viscosity control agents which can also act like or augmentthe effect of the surfactant concentration aids, include water-soluble,ionizable salts which can also optionally be incorporated into thecompositions of the present invention. A wide variety of ionizable saltscan be used. Examples of suitable salts are the halides of the Group IAand IIA metals of the Periodic Table of the Elements, e.g., calciumchloride, magnesium chloride, sodium chloride, potassium bromide, andlithium chloride. The ionizable salts are particularly useful during theprocess of mixing the ingredients to make the compositions herein, andlater to obtain the desired viscosity. The amount of ionizable saltsused depends on the amount of active ingredients used in thecompositions and can be adjusted according to the desires of theformulator. Typical levels of salts used to control the compositionviscosity are from 20 to 20,000 parts per million (ppm), preferably from20 to 11,000 ppm, by weight of the composition.

Alkylene polyammonium salts can be incorporated into the composition togive viscosity control in addition to or in place of the water-soluble,ionizable salts above. In addition, these agents can act as scavengers,forming ion pairs with anionic detergent carried over from the mainwash, in the rinse, and on the fabrics, and may improve softnessperformance. These agents may stabilize the viscosity over a broaderrange of temperature, especially at low temperatures, compared to theinorganic electrolytes.

Specific examples of alkylene polyammonium salts include I-lysinemonohydrochloride and 1,5-diammonium 2-methyl pentane dihydrochloride.

Another optional, but preferred, ingredient is a liquid carrier. Theliquid carrier employed in the instant compositions is preferably atleast primarily water due to its low cost, relative availability,safety, and environmental compatibility. The level of water in theliquid carrier is preferably at least 50%, most preferably at least 60%,by weight of the carrier. Mixtures of water and low molecular weight,e.g., <200, organic solvent, e.g., lower alcohols such as ethanol,propanol, isopropanol or butanol are useful as the carrier liquid. Lowmolecular weight alcohols include monohydric, dihydric (glycol, etc.)trihydric (glycerol, etc.), and higher polyhydric (polyols) alcohols.

Still other optional ingredients are Soil Release Polymers,bacteriocides, colorants, perfumes, preservatives, optical brighteners,anti ionisation agents, antifoam agents, and the like.

Various other optional adjunct ingredients may also be used to providefully-formulated detergent compositions. The following ingredients aredescribed for the convenience of the formulator, but are not intended tobe limiting thereof.

Detersive Ingredient

Detersive ingredients may also be used in the composition of theinvention. Suitable detersive ingredients are those conventional to thedetergent formulators of laundry and cleaning products. Typical of suchconventional detersive ingredients include detersive surfactants,builders, bleaching compounds, and mixtures thereof.

Detersive Surfactants

Nonlimiting examples of surfactants useful herein typically at levelsfrom 1% to 55%, by weight, include the conventional C₁₁ -C₁₈ alkylbenzene sulfonates ("LAS") and primary, branched-chain and random C₁₀-C₂₀ alkyl sulfates ("AS"), the C₁₀ -C₁₈ secondary (2,3) alkyl sulfatesof the formula CH₃ (CH₂)_(x) (CHOSO₃ ⁻ M⁺) CH₃ and CH₃ (CH₂)_(y) (CHOSO₃^(-M) ⁺) CH₂ CH₃ where x and (y+1) are integers of at least 7,preferably at least 9, and M is a water-solubilizing cation, especiallysodium, unsaturated sulfates such as oleyl sulfate, the C₁₀ -C₁₈ alkylalkoxy sulfates ("AE_(x) S"; especially x up to 7 EO ethoxy sulfates),C₁₀ -C₁₈ alkyl alkoxy carboxylates (especially the EO 1-5ethoxycarboxylates), the C₁₀ -₁₈ glycerol ethers, the C₁₀ -C₁₈ alkylpolyglycosides and their corresponding sulfated polyglycosides, and C₁₂-C₁₈ alpha-sulfonated fatty acid esters. If desired, the conventionalnonionic and amphoteric surfactants such as the C₁₂ -C₁₈ alkylethoxylates ("AE") including the so-called narrow peaked alkylethoxylates and C₆ -C₁₂ alkyl phenol alkoxylates (especially ethoxylatesand mixed ethoxy/propoxy), C₁₂ -C₁₈ betaines and sulfobetaines("sultaines"), C₁₀ -C₁₈ amine oxides, cationic surfactants and the like,can also be included in the overall compositions. The C₁₀ -C₁₈ N-alkylpolyhydroxy fatty acid amides can also be used. Typical examples includethe C₁₂ -C₁₈ N-methylglucamides. See WO 9,206,154. Other sugar-derivedsurfactants include the N-alkoxy polyhydroxy fatty acid amides, such asC₁₀ -C₁₈ N-(3-methoxypropyl) glucamide. The N-propyl through N-hexyl C₁₂-C₁₈ glucamides can be used for low sudsing. C₁₀ -C₂₀ conventional soapsmay also be used. If high sudsing is desired, the branched-chain C₁₀-C₁₆ soaps may be used. Mixtures of anionic and nonionic surfactants areespecially useful. Other conventional useful surfactants are listed instandard texts.

Builders

Detergent builders can optionally be included in the compositions hereinto assist in controlling mineral hardness. Inorganic as well as organicbuilders can be used. Builders are typically used in fabric launderingcompositions to assist in the removal of particulate soils.

The level of builder can vary widely depending upon the end use of thecomposition and its desired physical form. When present, thecompositions will typically comprise at least 1% builder, preferablyfrom 1% to 80%. Liquid formulations typically comprise from 5% to 50%,more typically 5% to 30%, by weight, of detergent builder. Granularformulations typically comprise from 1% to 80%, more typically from 5%to 50% by weight, of the detergent builder. Lower or higher levels ofbuilder, however, are not meant to be excluded.

Inorganic or P-containing detergent builders include, but are notlimited to, the alkali metal, ammonium and alkanolammonium salts ofpolyphosphates (exemplified by the tripolyphosphates, pyrophosphates,and glassy polymeric meta-phosphates), phosphonates, phytic acid,silicates, carbonates (including bicarbonates and sesquicarbonates),sulphates, and aluminosilicates. However, non-phosphate builders arerequired in some locales. Importantly, the compositions herein functionsurprisingly well even in the presence of the so-called "weak" builders(as compared with phosphates) such as citrate, or in the so-called"underbuilt" situation that may occur with zeolite or layered silicatebuilders.

Examples of silicate builders are the alkali metal silicates,particularly those having a SiO₂ :Na₂ O ratio in the range 1.0:1 to3.2:1 and layered silicates, such as the layered sodium silicatesdescribed in U.S. Pat. No. 4,664,839. NaSKS-6 is the trademark for acrystalline layered silicate marketed by Hoechst (commonly abbreviatedherein as "SKS-6"). Unlike zeolite builders, the Na SKS-6 silicatebuilder does not contain aluminum. NaSKS-6 has the delta-Na₂ SiO₅morphology form of layered silicate. It can be prepared by methods suchas those described in German DE-A-3,417,649 and DE-A-3,742,043. SKS-6 isa highly preferred layered silicate for use herein, but other suchlayered silicates, such as those having the general formula NaMSi_(x)O_(2x+1).yH₂ O wherein M is sodium or hydrogen, x is a number from 1.9to 4, preferably 2, and y is a number from 0 to 20, preferably 0 can beused herein. Various other layered silicates from Hoechst includeNaSKS-5, NaSKS-7 and NaSKS-11, as the alpha, beta and gamma forms. Asnoted above, the delta-Na₂ SiO₅ (NaSKS-6 form) is most preferred for useherein. Other silicates may also be useful such as for example magnesiumsilicate, which can serve as a crispening agent in granularformulations, as a stabilizing agent for oxygen bleaches, and as acomponent of suds control systems.

Examples of carbonate builders are the alkaline earth and alkali metalcarbonates as disclosed in German Patent Application No. 2,321,001published on Nov. 15, 1973.

Aluminosilicate builders are useful in the present invention.Aluminosilicate builders are of great importance in most currentlymarketed heavy duty granular detergent compositions, and can also be asignificant builder ingredient in liquid detergent formulations.Aluminosilicate builders include those having the empirical formula:

    M.sub.z/n [(AlO.sub.2).sub.z (SiO.sub.2).sub.y ].xH.sub.2 O

wherein z and y are integers usually of at least 6, the molar ratio of zto y is in the range from 1.0 to 0, and x is an integer from 0 to 264,and M is a Group IA or IIA element, e.g., Na, K, Mg, Ca with valence n.Useful aluminosilicate ion exchange materials are commerciallyavailable. These aluminosilicates can be crystalline or amorphous instructure and can be naturally-occurring aluminosilicates orsynthetically derived. A method for producing aluminosilicate ionexchange materials is disclosed in U.S. Pat. No. 3,985,669, Krummel, etal, issued Oct. 12, 1976. Preferred synthetic crystallinealuminosilicate ion exchange materials useful herein are available underthe designations Zeolite A, Zeolite P (B), Zeolite MAP and Zeolite X. Inan especially preferred embodiment, the crystalline aluminosilicate ionexchange material has the formula:

    Na.sub.12 [(AlO.sub.2).sub.12 (SiO.sub.2).sub.12 ].xH.sub.2 O

wherein x is from 20 to 30, especially 27. This material is known asZeolite A. Dehydrated zeolites (x=0-10) may also be used herein.Preferably, the aluminosilicate has a particle size of 0.1-10 microns indiameter.

Organic detergent builders suitable for the purposes of the presentinvention include, but are not restricted to, a wide variety ofpolycarboxylate compounds. As used herein, "polycarboxylate" refers tocompounds having a plurality of carboxylate groups, preferably at least3 carboxylates. Polycarboxylate builder can generally be added to thecomposition in acid form, but can also be added in the form of aneutralized salt. When utilized in salt form, alkali metals, such assodium, potassium, and lithium, or alkanolammonium salts are preferred.

Included among the polycarboxylate builders are a variety of categoriesof useful materials. One important category of polycarboxylate buildersencompasses the ether polycarboxylates, including oxydisuccinate, asdisclosed in Berg, U.S. Pat. No. 3,128,287, issued Apr. 7, 1964, andLamberti et al, U.S. Pat. No. 3,635,830, issued Jan. 18, 1972. See also"TMS/TDS" builders of U.S. Pat. No. 4,663,071, issued to Bush et al, onMay 5, 1987. Suitable ether polycarboxylates also include cycliccompounds, particularly alicyclic compounds, such as those described inU.S. Pat. Nos. 3,923,679; 3,835,163; 4,158,635; 4,120,874 and 4,102,903.

Other useful detergency builders include the etherhydroxypolycarboxylates, copolymers of maleic anhydride with ethylene orvinyl methyl ether, 1, 3, 5-trihydroxy benzene-2, 4, 6-trisulphonicacid, and carboxymethyloxysuccinic acid, the various alkali metal,ammonium and substituted ammonium salts of polyacetic acids such asethylenediamine tetraacetic acid and nitrilotriacetic acid, as well aspolycarboxylates such as mellitic acid, pyromellitic, succinic acid,oxydisuccinic acid, polymaleic acid, benzene 1,3,5-tricarboxylic acid,carboxymethyloxysuccinic acid, and soluble salts thereof.

Citrate builders, e.g., citric acid and soluble salts thereof(particularly sodium salt), are polycarboxylate builders of particularimportance for heavy duty liquid detergent formulations due to theiravailability from renewable resources and their biodegradability.Citrates can also be used in granular compositions, especially incombination with zeolite and/or layered silicate builders.Oxydisuccinates are also especially useful in such compositions andcombinations.

Also suitable in the detergent compositions of the present invention arethe 3,3-dicarboxy-4-oxa-1,6-hexanedioates and the related compoundsdisclosed in U.S. Pat. No. 4,566,984, Bush, issued Jan. 28, 1986. Usefulsuccinic acid builders include the C₅ -C₂₀ alkyl and alkenyl succinicacids and salts thereof. A particularly preferred compound of this typeis dodecenylsuccinic acid. Specific examples of succinate buildersinclude: laurylsuccinate, myristytsuccinate, palmitylsuccinate,2-dodecenylsuccinate (preferred), 2 pentadecenylsuccinate, and the like.Laurylsuccinates are the preferred builders of this group, and aredescribed in EP 0,200,263.

Other suitable polycarboxylates are disclosed in U.S. Pat. No. 4,144,226and in U.S. Pat. No. 3,308,067. See also U.S. Pat. No. 3,723,322.

Fatty acids, e.g., C₁₂ -C₁₈ monocarboxylic acids such as oleic acidand/or its salts, can also be incorporated into the compositions alone,or in combination with the aforesaid builders, especially citrate and/orthe succinate builders, to provide additional builder activity. Such useof fatty acids will generally result in a diminution of sudsing, whichshould be taken into account by the formulator.

In situations where phosphorus-based builders can be used, andespecially in the formulation of bars used for hand-launderingoperations, the various alkali metal phosphates such as the well-knownsodium tripolyphosphates, sodium pyrophosphate and sodium orthophosphatecan be used. Phosphonate builders such asethane-1-hydroxy-1,1-diphosphonate and other known phosphonates (see,for example, U.S. Pat. Nos. 3,159,581; 3,213,030; 3,422,021; 3,400,148and 3,422,137) can also be used.

Bleaching Compounds--Bleaching Agents and Bleach Activators

The detergent compositions herein may optionally contain bleachingagents or bleaching compositions containing a bleaching agent and one ormore bleach activators. When present, bleaching agents will typically beat levels of from 1% to 30%, more typically from 5% to 20%, of thedetergent composition, especially for fabric laundering. If present, theamount of bleach activators will typically be from 0.1% to 60%, moretypically from 0.5% to 40% of the bleaching composition comprising thebleaching agent-plus-bleach activator.

The bleaching agents used herein can be any of the bleaching agentsuseful for detergent compositions in textile cleaning or other cleaningpurposes that are now known or become known. These include oxygenbleaches as well as other bleaching agents. Perborate bleaches, e.g.,sodium perborate (e.g., mono- or tetra-hydrate) can be used herein.

Another category of bleaching agent that can be used without restrictionencompasses percarboxylic acid bleaching agents and salts thereof.Suitable examples of this class of agents include magnesiummonoperoxyphthalate hexahydrate, the magnesium salt of metachloroperbenzoic acid, 4-nonylamino-4-oxoperoxybutyric acid anddiperoxydodecanedioic acid. Such bleaching agents are disclosed in U.S.Pat. No. 4,483,781, U.S. 740,446, EP 0,133,354, and U.S. Pat. No.4,412,934. Highly preferred bleaching agents also include6-nonylamino-6-oxoperoxycaproic acid as described in U.S. Pat. No.4,634,551.

Peroxygen bleaching agents can also be used. Suitable peroxygenbleaching compounds include sodium carbonate peroxyhydrate andequivalent "percarbonate" bleaches, sodium pyrophosphate peroxyhydrate,urea peroxyhydrate, and sodium peroxide. Persulfate bleach (e.g., OXONE,manufactured commercially by DuPont) can also be used.

A preferred percarbonate bleach comprises dry particles having anaverage particle size in the range from 500 micrometers to 1,000micrometers, not more than 10% by weight of said particles being smallerthan 200 micrometers and not more than 10% by weight of said particlesbeing larger than 1,250 micrometers. Optionally, the percarbonate can becoated with silicate, borate or water-soluble surfactants. Percarbonateis available from various commercial sources such as FMC, Solvay andTokai Denka.

Mixtures of bleaching agents can also be used.

Peroxygen bleaching agents, the perborates, the percarbonates, etc., arepreferably combined with bleach activators, which lead to the in situproduction in aqueous solution (i.e., during the washing process) of theperoxy acid corresponding to the bleach activator. Various nonlimitingexamples of activators are disclosed in U.S. Pat. No. 4,915,854, andU.S. Pat. No. 4,412,934. The nonanoyloxybenzene sulfonate (NOBS),3,5,5-tri-methyl hexanoyl oxybenzene sulfonate (ISONOBS) and tetraacetylethylene diamine (TAED) activators are typical, and mixtures thereof canalso be used. See also U.S. Pat. No. 4,634,551 for other typicalbleaches and activators useful herein.

Highly preferred amido-derived bleach activators are those of theformulae:

    R.sup.1 N(R.sup.5)C(O)R.sup.2 C(O)L or R.sup.1 C(O)N(R.sup.5)R.sup.2 C(O)L

wherein R¹ is an alkyl group containing from 6 to 12 carbon atoms, R² isan alkylene containing from 1 to 6 carbon atoms, R⁵ is H or alkyl, aryl,or alkaryl containing from 1 to 10 carbon atoms, and L is any suitableleaving group. A leaving group is any group that is displaced from thebleach activator as a consequence of the nucleophilic attack on thebleach activator by the perhydrolysis anion. A preferred leaving groupis phenyl sulfonate.

Preferred examples of bleach activators of the above formulae include(6-octanamido-caproyl)oxybenzenesulfonate,(6-nonanamidocaproyl)-oxybenzenesulfonate,(6-decanamido-caproyl)oxybenzenesulfonate, and mixtures thereof asdescribed in U.S. Pat. No. 4,634,551, incorporated herein by reference.

Another class of bleach activators comprises the benzoxazin-typeactivators disclosed by Hodge et al in U.S. Pat. No. 4,966,723. A highlypreferred activator of the benzoxazin-type is: ##STR32##

Still another class of preferred bleach activators includes the acyllactam activators, especially acyl caprolactams and acyl valerolactamsof the formulae: ##STR33## wherein R⁶ is H or an alkyl, aryl,alkoxyaryl, or alkaryl group containing from 1 to 12 carbon atoms.Highly preferred lactam activators include benzoyl caprolactam, octanoylcaprolactam, 3,5,5-trimethylhexanoyl caprolactam, nonanoyl caprolactam,decanoyl caprolactam, undecenoyl caprolactam, benzoyl valerolactam,octanoyl valerolactam, decanoyl valerolactam, undecenoyl valerolactam,nonanoyl valerolactam, 3,5,5-trimethylhexanoyl valerolactam and mixturesthereof. See also U.S. Pat. No. 4,545,784, issued to Sanderson, Oct. 8,1985, incorporated herein by reference, which discloses acylcaprolactams, including benzoyl caprolactam, adsorbed into sodiumperborate.

Bleaching agents other than oxygen bleaching agents are also known inthe art and can be utilized herein. One type of non-oxygen bleachingagent of particular interest includes photoactivated bleaching agentssuch as the sulfonated zinc and/or aluminum phthalocyanines. See U.S.Pat. No. 4,033,718, issued Jul. 5, 1977 to Holcombe et al. If used,detergent compositions will typically contain from 0.025% to 1.25%, byweight, of such bleaches, especially sulfonate zinc phthalocyanine.

If desired, the bleaching compounds can be catalyzed by means of amanganese compound. Such compounds are well known in the art andinclude, for example, the manganese-based catalysts disclosed in U.S.Pat. No. 5,246,621, U.S. Pat. No. 5,244,594; U.S. Pat. No. 5,194,416;U.S. Pat. No. 5,114,606; and EP 549,271A1, 549,272A1, 544,440A2, and544,490A1; Preferred examples of these catalysts include Mn^(IV) ₂(u-O)₃ (1,4,7-trimethyl-1,4,7-triazacyclononane)₂ (PF₆)₂, Mn^(III) ₂(u-O)₁ (u-OAc)₂ (1,4,7-trimethyl-1,4,7-triazacyclononane)₂ -(ClO₄)₂,Mn^(IV) ₄ (u-O)₆ (1,4,7-triazacyclononane)₄ (ClO₄)₄, Mn^(III) Mn^(IV) ₄(u-O)₁ (u-OAc)₂₋ (1,4,7-trimethyl-1,4,7-triazacyclononane)₂ (ClO₄)₃,Mn^(IV) (1,4,7-trimethyl-1,4,7-triazacyclononane)-(OCH₃)₃ (PF₆), andmixtures thereof. Other metal-based bleach catalysts include thosedisclosed in U.S. Pat. No. 4,430,243 and U.S. Pat. No. 5,114,611. Theuse of manganese with various complex ligands to enhance bleaching isalso reported in the following U.S. Pat. Nos. 4,728,455; 5,284,944;5,246,612; 5,256,779; 5,280,117; 5,274,147; 5,153,161; and 5,227,084.

As a practical matter, and not by way of limitation, the compositionsand processes herein can be adjusted to provide on the order of at leastone part per ten million of the active bleach catalyst species in theaqueous washing liquor, and will preferably provide from 0.1 ppm to 700ppm, more preferably from 1 ppm to 500 ppm, of the catalyst species inthe laundry liquor.

Other preferred optional ingredients include enzymes such as lipases,proteases, amylases and peroxidases, enzyme stabilisers, polymeric soilrelease agents, materials effective for inhibiting the transfer of dyesfrom one fabric to another during the cleaning process (i.e., dyetransfer inhibiting agents), polymeric dispersing agents, sudssuppressors, optical brighteners or other brightening or whiteningagents, chelating agents, fabric softening clay, anti-static agents,other active ingredients, carriers, hydrotropes, processing aids, dyesor pigments, solvents for liquid formulations and solid fillers for barcompositions.

Liquid detergent compositions can contain water and other solvents ascarriers. Low molecular weight primary or secondary alcohols exemplifiedby methanol, ethanol, propanol, and isopropanol are suitable. Monohydricalcohols are preferred for solubilizing surfactant, but polyols such asthose containing from 2 to 6 carbon atoms and from 2 to 6 hydroxy groups(e.g., 1,3-propanediol, ethylene glycol, glycerine, and 1,2-propanediol)can also be used. The compositions may contain from 5% to 90%, typically10% to 50% of such carriers.

Granular detergents can be prepared, for example, by spray-drying (finalproduct density 520 g/l) or agglomerating (final product density above600 g/l) the Base Granule. The remaining dry ingredients can then beadmixed in granular or powder form with the Base Granule, for example ina rotary mixing drum, and the liquid ingredients (e.g., nonionicsurfactant and perfume) can be sprayed on.

The detergent compositions herein will preferably be formulated suchthat, during use in aqueous cleaning operations, the wash water willhave a pH of between 6.5 and 1 1, preferably between 7.5 and 10.5.Laundry products are typically at pH 9-11. Techniques for controlling pHat recommended usage levels include the use of buffers, alkalis, acids,etc., and are well known to those skilled in the art.

Method

In another aspect of the invention, there is provided a method forproviding color care and perfume substantivity on fabrics upon domestictreatment which comprises the step of contacting the fabrics with anaqueous medium comprising a composition as defined hereinbefore.Preferably, said aqueous medium is at a temperature between 2 to 40° C.,more preferably between 5 to 25° C.

In a further aspect of the invention, the composition of the inventionmay be applied on a substrate, such as a dryer-sheet. Accordingly, thereis also provided a method for providing color care and perfumesubstantivity on fabrics upon domestic treatment which comprises thestep of contacting the fabrics with a composition as definedhereinbefore, wherein said composition is applied on a substrate,preferably a dryer-sheet. Preferably, where the composition of theinvention is applied on a dryer-sheet, the compositions are used intumble-drying processes.

By "effective perfume substantivity on the fabric", it is meant that thefabrics which are contacted with a composition of the invention exhibita better or equal perfume substantivity on the fabric compared tocompositions which comprise the hydrophilic perfume but not theamino-functional polymer.

The benefit of perfume substantivity on the treated fabric may beassessed by evaluating the intensity of the perfume on wet and dryfabrics. The method is carried out by a panel of 6 expert judges,trained to use sensory evaluations. In this instance, expert is definedas a person having at least 6 months training with demonstrated evidenceof olfactive sensitivity. The data obtained using the perfumersintensity scale are then averaged to give a consensus value for theperceived intensity of perfume.

The perfumers intensity scale is as follows:

0--no perfume,

25--slight perfume,

50--moderate perfume,

75--very strong perfume, and

100--extremely strong perfume

By "color care", it is meant that fabrics which have been in contactwith a composition of the invention, as defined hereinbefore, and whichafter, and/or prior and/or simultaneously washed with a detergentcomposition exhibit a better fabric color appearance compared to fabricswhich have not been contacted with said composition.

The color care benefit may either be assessed visually or bydetermination of the so-called delta-E values.

When the visual assessment is used, a panel of expert graders visuallycompare, according to the established panel score unit (PSU) scales,fabrics treated with and without the composition according to thepresent invention. A positive PSU value indicates a better performance(PSU scale: 0=no difference, 1=I think there is a difference, 2=I knowthere is a difference, 3=I know there is a lot of difference, 4=I knowthere is a whole lot of difference).

Another method for the assessment of the color care benefit to fabricsis the determination of the so-called delta-E values. Delta E's aredefined, for instance, in ASTM D2244. Delta E is the computed colordifference as defined in ASTM D2244, i.e the magnitude and direction ofthe difference between two psychophysical color stimuli defined bytristimulus values, or by chromaticity coordinates and luminance factor,as computed by means of a specified set of color-difference equationsdefined in the CIE 1976 CIELAB opponent-color space, the Hunteropponent-color space, the Friele-Mac Adam-Chickering color space or anyequivalent color space.

Applications

The compositions of the invention are suitable for use in any steps ofthe domestic treatment, that is as a pre-treatment composition, as awash additive as a composition suitable for use in the rinse-cycle ofthe laundry cycle or applied on a dryer-sheet. Obviously, for thepurpose of the invention, multiple applications can be made such astreating the fabric with a pre-treatment composition of the inventionand also thereafter with a composition of the invention suitable for usein the rinse cycle and/or suitable for use as a dryer-sheet. Thecompositions of the invention may also be in a spray, foam, or aerosolform which for example can be suitable for use while ironing, or appliedon the surfaces of the tumble dryer.

The invention is illustrated in the following non limiting examples, inwhich all percentages are on an active weight basis unless otherwisestated.

SYNTHESIS EXAMPLE 1

Preparation of PEI 1800 E₁

Step A)-The ethoxylation is conducted in a 2 gallon stirred stainlesssteel autoclave equipped for temperature measurement and control,pressure measurement, vacuum and inert gas purging, sampling, and forintroduction of ethylene oxide as a liquid. A ˜20 lb. net cylinder ofethylene oxide (ARC) is set up to deliver ethylene oxide as a liquid bya pump to the autoclave with the cylinder placed on a scale so that theweight change of the cylinder could be monitored.

A 750 g portion o f polyethyleneimine (PEI) (Nippon Shokubai, EpominSP-018 having a listed average molecular weight of 1800 equating to0.417 moles of polymer and 17.4 moles of nitrogen functions) is added tothe autoclave. The autoclave is then sealed and purged of air (byapplying vacuum to minus 28" Hg followed by pressurization with nitrogento 250 psia, then venting to atmospheric pressure). The autoclavecontents are heated to 130° C. while applying vacuum. After about onehour, the autoclave is charged with nitrogen to about 250 psia whilecooling the autoclave to about 105° C. Ethylene oxide is then added tothe autoclave incrementally over time while closely monitoring theautoclave pressure, temperature, and ethylene oxide flow rate. Theethylene oxide pump is turned off and cooling is applied to limit anytemperature increase resulting from any reaction exotherm. Thetemperature is maintained between 100 and 110° C. while the totalpressure is allowed to gradually increase during the Course of thereaction. After a total of 750 grams of ethylene oxide has been chargedto the autoclave (roughly equivalent to one mole ethylene oxide per PEInitrogen function), the temperature is increased to 110° C. and theautoclave is allowed to stir for an additional hour. At this point,vacuum is applied to remove any residual unreacted ethylene oxide.

Step B)-The reaction mixture is then deodorized by passing about 100 cu.ft. of inert gas (argon or nitrogen) through a gas dispersion frit andthrough the reaction mixture while agitating and heating the mixture to130° C.

The final reaction product is cooled slightly and collected in glasscontainers purged with nitrogen.

In other preparations the neutralization and deodorization isaccomplished in the reactor before discharging the product.

If a PEI 1800 E₇ is desired, the following step of catalyst additionwill be included between Step A and B.

Vacuum is continuously applied while the autoclave is cooled to about50° C. while introducing 376 g of a 25% sodium methoxide in methanolsolution (1.74 moles, to achieve a 10% catalyst loading based upon PEInitrogen functions). The methoxide solution is sucked into the autoclaveunder vacuum and then the autoclave temperature controller setpoint isincreased to 130° C. A device is used to monitor the power consumed bythe agitator. The agitator power is monitored along with the temperatureand pressure. Agitator power and temperature values gradually increaseas methanol is removed from the autoclave and the viscosity of themixture increases and stabilizes in about 1 hour indicating that most ofthe methanol has been removed. The mixture is further heated andagitated under vacuum for an additional 30 minutes. Vacuum is removedand the autoclave is cooled to 105° C. while it is being charged withnitrogen to 250 psia, and then vented to ambient pressure. The autoclaveis charged to 200 psia with nitrogen. Ethylene oxide is again added tothe autoclave incrementally as before while closely monitoring theautoclave pressure, temperature, and ethylene oxide flow rate whilemaintaining the temperature between 100 and 110 ° C. and limiting anytemperature increases due to reaction exotherm. After the addition of4500 g of ethylene oxide (resulting in a total of 7 moles of ethyleneoxide per mole of PEI nitrogen function) is achieved over several hours,the temperature is increased to 110° C. and the mixture stirred for anadditional hour.

The reaction mixture is then collected in nitrogen purged containers andeventually transferred into a 22 L three neck round bottomed flaskequipped with heating and agitation. The strong alkali catalyst isneutralized by adding 167 g methanesulfonic acid (1.74 moles).

Other preferred examples such as PEI 1800 E2, PEI 1800 E3, PEI 1800 E15and PEI 1800 E20 can be prepared by the above method by adjusting thereaction time and the relative amount of ethylene oxide used in thereaction.
